| Abstract: | Dimethyl Carbonate were synthemed from urea and methanol in ionic liquids in the work..The highly productive conditions were explored by using orthogonal expenriment design.Through compareing the results of range analysis and variance analysis,the idea sythemitic conditions of dimethyl carbonate from urea and methanol in ionic liquid were as follows：at 150℃,at 1 of the ratio of ironic liquid to urea,and for 7 hours. |
